I got a 18.5 inch barrel on a Blaser... get 2800-2900 with a Barnes 120TTSX but not that accurate... have pretty much settled on a 100r TTSX at 3100 which has 3 shot groups under 20mm consistently. Am going to chop another 2 inches off it and have it suppressed all the time.. still good to 350 with this setup...
if you are staying under 300 or so, not a lot of point in worrying about the ballistic superiority of the 140 AMAX... personally I would fling a better constructed and lighter pill a little faster.. If you can get the 120TTSX to work well, its a brilliant choice for under 400m
